Phone Jack Wiring Instructions

Step #1: Choose the type of phone jack mounting you want to conduct, whether a surface mount or a wall mount, whatever it is, the wiring is the same.

Step #2: Once you choose your type of mounting, remove the front cover of the device and you will see 4 screw terminals with colored wires present in them. Use a flat-head screwdriver to loosen all the four wires.

Step #3: To add an insulation from each of your phone wires, strip about ¾” of strips using a wire stripper. Ensure that you do not cut the phone wire in the process, because the phone cables are very gentle and thin.

Step #4: After the phone’s four wires are stripped and installed, get hold of the phone jack and begin to wrap each wire around the terminal points. Match the similar colors while attaching, for instance if there is a green wire in the phone jack, attach the green wire around the terminal screw carefully. Tighten the screw to fasten the wire properly.

Step #5: Well, this is just one example for one wire. Similarly, perform for the remaining 3 wires and look for a notch in the device of the phone jack. If you are able to find that, slowly place the insulated-sheathed part of the phone lines in it to give it a neat and professional look.

Step #6: In the final step, just replace the cover of the phone jack and screw all the screws back into its place, the way it was. This is where you complete the entire procedure of wiring.

Remember, the phone jack is always provided with two lines in a pair; yellow and black and red and green. You may remember this combination as Bumble Bees and Christmas Trees concurrently.
